On the one hand, you could take the cynical route with this because Harrison Ford is clearly being paid to do this as an advertisement ala Bill Murray in Lost In Translation, but on the other hand it’s Indiana Jones playing a game that is essentially a 15 hour long homage to his work.
I don’t know whether to be more impressed that Harrison is actually playing and progressing in a fairly “hardcore” game or that he’s making a video of someone playing a video game not look like a 7-minute long mouth breathing sequence.
I suppose he is a thespian by trade, after all.
